The invention relates to heat exchange devices such as are used for the purpose of heating apartments, dwellings, etc., and has as its principal object the provision of a construction whereby air may be heated by radiation, conduction and convection.

The invention has as an object the provision of a device of this character having means through which the heating medium is circulated having an element extending therefrom which is heated by conduction by said means, said means and said element being arranged relatively to eachother so that air contacting therewith'will b e heated and by means of convection, be circulated into the` room to be heated. A further object of the invention is to construct the device so Vas to provide a radiator, having an element which is heated by conduction, said radiator and element providing a plurality of vertically arranged fines producing air passages which g the upper portion of the casing.

It is an object to construct the radiator portion of the device through which the heating medium circulates so that a plurality of extensions and recesses are provided between read in conjunction with the accompanyingdrawing which discloses two arrangements which may beA resorted to,'it being obvious that changes and modifications may be resorted to without departing from the spirit ot the appended claims forming a part hereof.

In the drawing: Fig. 1 is a front view partially broken away for the purpose of illustration;

Fig. 2 is an enlarged section taken on line 2-'f2of Fig. 1;

. Fig. 3 is a sectional View similar to Fig. 2 showing a modified arrangement;

F ig. 4 is a horizontal section taken on line 4-4 of Fig. 3; and

F-ig. 5 is a perspective yiew of a portion of the structure-shown in F1 3.

The structure disclosed in the drawing for accomplishing the advantages above enumerated contemplates the utilization of a radiator section generally designated 10 having the iiuid inlet and outlet pipes respectivel designated 114 and 12 connected therewith.

ne wall of the radiator or heat exchange device' generally designated 10 is provided with an element 13 which extends a suitable distance beyond the upper edge of the heat exchange device and has itsl upper end pref-v erably connected with a wall-14; of a casing enerally designated'l. The side walls 16 and 17 of the casing are connected with the heat exchange device 10 and the extension 13 thereof, by an suitable means and therefore may be welde or bolted together. The heat exchange'device 10 including the extension 13 is arranged relatively to the lowermost end of the casing to provide an opening 18.

In one embodiment of the invention, the heat exchange device 10 is arranged in spaced relation to the rear wall 15 of the casing and thus as relatively cool air enters the opening 18, said air will contact with the heat exchange device 10, become heated and by convection be transmitted through the casing and out through the openings 19' provided in the upper end of the extension 13. .The front wall of the heat exchange device generally designated 10 of which the element 1,3 is a part is provided with a plurality of recesses and extensions respectively designated 20 and 21 and the rear wall such as 22 of the heat` exchange device is similarly formed, it being understood thatthe edges of the rear wall 22 l and the front wall of the heat exchange device are connected together in a manner to provide the end walls of the radiator l0 and may be connected together in any Suitable manner, as for instance, by the lock seams 23 and 24. The open ends of the structure thus formed welded or otherwise secured in place to provide a chamber or radiator through which the heating medium may circulate to transmit heat to the extension 13 forming the front wall thereof and also heat that air passing through the opening 18 into and out ofthe casing within which the device is located.

It is one of the objects of the invention to provide a construction of this character which will allow relatively thin and cheap4 material to be employed in the formation of the structure and provision is made to add strength and life to the device by the resistance to rust and corrosion. To this end, the heat exchange device or radiator section 10 is provided with an inner lining 27. which conforms to the outline of the tank or radiator section 10.

It is evident from the'oregoing explanation of the relative arrangement or" radiator section 1() and the extension 13 that this arrangement of these parts forms a recess generally designated 28 4which is located above the radiator and thus a 'portion of the air entering the opening 18 will Contact with the inner face of the extension 13, and. thus retain the heat transmitted to it by virtue of its contact with the wall 22 of the radiator 10, and reduce its heat loss as it is evident that the heated extension 13 will assist in heating the air somewhat, prior to discharge ot the heated air through the openings 19 of the casing, It is contemplated to employ a humidiier 29 and to arrange the humidifier in the upper portion of the casing in a manner to allow heated air to pass between the humidier and the wall 15 of the casing and thence over the open end of the humidifier and out into the room. The humidifier may, it so desired, be provided with the curved wall 30 which will act to deflect the heated air toward the openings 19 provided in the extension 13.

Another embodiment of the invention contemplates the utilization ot heat radiating fins 31 which maybe of any one ot many con structions, that herein shown being comprised of a band ot metal which'is corrugated to provide a plurality of tubular passages and recesses respectively designated 532-33, be-

r' tri/en which the relative?, `Yool ainpasses and is partially heated thereby prior to its engagement with the rear wall 22 of the radiator 10.

From the foregoing description ot the structure, it is manifest that a heat exchange device is provided whereby air is heated by radiation and conduction and caused to be discharged from the interior or" the casing by convection. It is further evident that by forming the radiator and the extension 13 thereof to provide a plurality of vertically arranged recesses and extensions that these, in edect, produce a plurality of Hues which guide the heated air in a manner to result 1n increasing the heating eliiciency of the device .and in addition increases the heat radiating closed, that a recess is formed above the radiator into which the heated air is discharged from theradiator, which will maintain the air at a degree substantially corresponding to that of the air as it leaves the radiator 10, it being manifest that a certain degree of heat is also radiated Jfrom the upper end oit the radiator sectionv 10 which is also transmitted to the heated air contained in the recess.
